Storing pre-mixed water

[FishFace28]

Is there any danger in storing pre-mixed salt water? If it sits for a week or even 2 or 3 before you use it, will it hurt anything?

I store 5 gallons of salt water in sealed water jugs. I have not seen any ill affects as of yet. Just make sure its sealed and you should be fine.

I let mine sit for 2-4 weeks. I only keep a heater on it in case I need emergency water but turn on a pump 2 days before I use it for water change. No problems here.
